ATTORNEYS l atented Feb. 27, 1934 UNITED STATES PATENT OFFMIE 2 Claims.

My invention relates to improvements in window constructions, and itconsists in the combinations, constructions, and arrangements hereindescribed and claimed.

An object of my invention is to provide a window construction havingnovel means whereby aligned windows may be opened.

A further and principal object of my invention is to provide a moresimple window construction than the window construction set forth in myapplication for patent Serial No. 449,950.

A further object is to provide a window construction having aligned topand bottom windows in which both windows may be moved vertically.

Another object is to provide novel means whereby aligned top and bottomwindows may be moved out of alignment and said top window may be removedfrom the window frame.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which Figure 1 is a front elevation of my windowconstruction,

Figure 2 is a section taken along the line 2--2 of Figure 1,

Figure 3 is a section taken along the line of Figure 1,

Figure 4 is a detail view showing a detachable locking means associatedwith the bottom window.

Figure 5 is a detail view of the structure whereby the top window may bemoved vertically and removed from the frame,

Figure 6 is a section taken along the line 6-6 of Figure 5, and

Figure '7 is a detail view of the catch means for locking said top andbottom windows in alignment.

In carrying out my invention I provide a window frame 1 comprising innerside portions 2, outer side portions 3, an inner lintel portion 4, anouter lintel portion 5, and a sill portion 6 as shown in Figure 1.

Referring to Figure 2 it will be seen that 1 provide a top window '7 anda bottom window 8 which are in alignment. Since both sides of the windowframe and the structure associated therewith are identical, thedescription will be confined to the structure associated with one sideof the window frame. A track member 9 is disposed in a substantiallyvertical position on the top portion of the inner side of the windowframe and is spaced away from the window frame as shown in Figure 5. Thetrack member 9 is provided with a leg formation 10 at each end thereofadapted for being connected with the window frame by any desirable meanssuch as screws 11. It will be noted by referring to Figure 6 that thetop end of said track member is slightly nearer to the top window sashthan the bottom end thereof. In other words the track member is notdisposed in a strictly vertical position and is not parallel to the topwindow. The purpose of this will be hereinafter described. A hook member12 as shown in Figures 5 and 6 is provided with a stem portion 13 havingtrack engaging formations 14 whereby the hook member may be slidablyconnected with the track 9. The hook member is provided with a slottedportion 15 and a slotted portion 16 which are disposed between the bodyportion of the hook and a projecting portion thereof, said slot 16 76terminating in recessed portions 18 and 19.

A chain, cable, or other suitable link means 20 is connected with thehook 12 through the slot 15 and extends through an opening 21 in theinner lintel portion of the frame and over rollers 22 for beingoperatively associated with a weight member 23. A plate member 24 isfixedly connected with the sash 25 of the top window 7 by any suitablemeans such as screws 26 and is provided with a flange portion 27 havinga stud portion 28 provided with a head 29. The stud portion 28 isnormally disposed in the recessed portion 19 of the hook member 12. Itwill be seen by referring to Figures 1 and 6 that a space is providedbetween the windows and the window frame.

On referring to Figures 1 and 7 it will be seen that the top portion ofthe bottom window sash is provided with a plate 30 adapted for beingsecured to the window sash by any suitable means such as screws 31. Acatch member 32 is pivotally or rotatably mounted on the plate member 30and is provided with a projecting or catch portion 33 and an actuatingor handle portion 34. The side 2 of the window frame is provided with anopening 35 therein. A plate member 36 is fixedly connected with the side2 of the window frame and is disposed over the opening 35. The plate 36is provided with a slot 3'7 therein for receiving the projecting orcatch portion 33. The plate 30 is provided with a bent over or flangeportion 38 which abuts the frame side of the window sash. The flangeportion 38 is provided with an opening therein for receiving a pin 39110 whereby the pin 39 may be fixedly connected therewith. The pin 39extends through a slot 40 in the side of the window frame and isconnected with a chain or cable 20 which extends over the pulleys 22'and is operatively connected with the window weight 23. The cableportions 20 and 20 may be integral as shown and operatively associatedwith the weight 23 by a pulley 44.

It will be seen by referring to Figure 2 that the slot 40 is composed ofslotted portions 41, 42, and 43. The bottom portion of the frame side isprovided with a track member of the shape shown in Figure 2. The top endof the track member is positioned adjacent the inner edge of the windowframe, the bottom edge of the track member extending toward the lowersash of the bottom window. The track 45 is provided with a slot 46 inthe top end portion thereof. The track is connected with the frame byany suitable means such as screws 47 but it will be noted that the lowerend of the track is not provided with any screws for being connectedwith the frame. The reason for this will be hereinafter explained. Acatch member 48 is mounted on the lower portion of the bottom windowsash adjacent the edge thereof by any desirable means such as screws 49.The catch member comprises a movable pin 50 having an actuating arm 51.The pin 50 is provided with a shoe portion 52 adapted for fitting overthe track 45 and slidable with respect thereto. A catch member 53 may bepivotally connected to the side of the window frame adjacent the lowerextremity of the track 45. The

' catch member 53 is provided with a hook portion 54 adapted forengaging the pin 50 when the lower window is in the position shown inFigure 2 whereby the bottom portion of said window may be locked againstvertical movement. A Weatherstrip 55 is provided having a bead portion56. The Weatherstrip is connected with each of the inner sides of thewindow frame and extends the full length thereof. Both the top andbottom windows are provided with recesses 57 for receiving the beadportion 56 when the windows are in their aligned position shown inFigures 1 and 2.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

When the operator desires to open the windows, he first grips thehandles 34 of the catch members 32 and rotates them for moving the catchportion 33 out of the slot in the plate 36. The bottom window is thenswung inwardly pivoting about the pin 50. At this point it will be seenthat the reason the bottom portion of the track is not connected withthe side of the window frame is that it must be resilient or movable asthe resistance of the weatherstrips 55 to the bottom edge of the windowsash when the window is being swung inwardly will tend to spring thelower end of the track. As the bottom window is swung inwardly, the pin39 moves through the slot portion 42 until it enters the slot 41. If itis desired to retain the bottom Window in this position, the catchportion 33 is moved for entering the slot 46 in the top portion of thetrack member. If it is desired that the bottom window be locked in thislatter position so that it cannot be moved upwardly from the outside 0fthe window by releasing the catch members 32, it will be merelynecessary to move the hook members 54 for engaging the pins 50. The hookmembers 54 may or may not be used as desired. When it is desired thatthe bottom window be moved upwardly the catch portions 33 are removedfrom the slots 46 in the top portion of the track members whereby thebottom window may be moved upwardly. As the window moves upwardly thepin 39 moves upwardly in the slot portion 41, said window beingsuspended in any desired position by the window weights 23. It will beseen by referring to Figure 3 that the pins 50 may be actuated forremoving the shoe portions 52 from the tracks 45 whereby the bottomportion of the bottom window may be swung upwardly.

It will be seen by referring to Figures 2 and 5 that a catch member 58is connected with each side of the window frame for normally holding thetop window sash in engagement with the window strips. When it is desiredthat the top window may be moved downwardly, it is first necessary thatthe bottom window be moved out of alignment therewith. When the topwindow is moved downwardly the catch members 12 slide downwardly on thetrack members 9, said top window being held in its suspended position bythe weights 23. When it is desired that the top window be swunginwardly, it is first necessary that the bottom window be swung inwardlyand then moved upwardly. The shoe members 52 are then moved out ofengagement with the tracks 45 whereby the bottom portion of the bottomwindow may be swung inwardly. The window is then moved downwardly inorder that the pins 39 may be moved into the slot portions 43. The catchmembers 58 are then moved toward the window frame whereby the top windowmay be released for being swung inwardly. As the top window swingsinwardly the resistance of the Weatherstrip against the top portion ofsaid window moves the studs 28 from the recess portion 19 and the hook12 to the recess portion 18 thereby preventing a binding action betweenthe window frame sash and the weatherstrips. If it is desired to removethe top window from the frame, it is merely necessary to slide the pins28 through the slots 16 and over the projections 17. As has beenreferred to hereinbefore the track members 9 are disposed in an inclinedposition with respect to the windows and window frame. The reason forthis is that as the top window is moved downwardly from its positionshown in Figure 2 it will be moved away from the weatherstrips therebypreventing a binding action between the window and the weather stripsand that when the window is returned to its position shown in Figure 5it will be slidingly moved into engagement.
